Hello all,
the documentation for the socket module says that gethostbyaddr should
return the primary host name and alternative host names if there are
any. But the alias list is empty even in cases where I know aliases
exist. I can get them using gethostbyname_ex, but that only works with
names, not with IP addresses, and I want to resolve both sorts.
I'm using Python 2.3.2 on Windows NT4, SP6.

I am fairly new to python and seem to have gotten ahead of myself. I
am trying to write a Windows service that will return the current
number of Citrix sessions to a client. This service will run on my
Citrix servers for usage tracking purposes.
The service itself seems to function properly, it starts, stops, logs
to the event viewer, etc. The problem seems to be with the portion
where it either waits to be stopped or waits for remote...

Hi,
I have a SunOS TCP/IP client program worked fine for a long time
until yesterday.
Now, my TCP/IP server program is located on different
DNS server.
The gethostbyaddr ( ) is now returned NULL instead.

I have a list of IP addresses I am testing with socket.gethostbyaddr().
For the most part, I am able to get a hostname returned to me when I
run gethostbyaddr(). I am also hoping this will allow me to tell if a
computer is up or down. However, in my environment, I am finding that I
am able to get a hostname even though I am unable to actually ping that
server (when I ping a server i like this, I get 'request timed out'
messages telling me...

Hi
Since yesterday about 11.00 CET the gethostbyaddr function doesn't seem
to be working. All I get is the IP address back. Is this something
general to all PHP users or is this specific to my server?
Thanks
BTW what's the difference between comp.lang.php, alt.php and
alt.comp.lang.php, shouldn't these groups be merged?

hi,
I came to know that gethostbyaddr is deprecated in Visual Studio 2005 by the introduction of getnameinfo function.
Can i know the reason for the deprecation of gethostbyaddr function.
Is there any security issues related with this function?
Also came to know that calling this function is not thread safe.
I am not able to get the exact reason for not using gethostbyaddr function.

When there is no rDNS record on an IP address, then it might take a while for
the reverse lookup to timeout. I'm thinking of how on a tracert you can
observe the delay.
If so, then calling gethostbyaddr() can delay the serving of the web page,
right? Because gethostbyaddr() is not forked into a separate process. So I
suppose I'd need to call gethostbyaddr() as the very last task for a script.
Does that sound right? Or is there another...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
